Looking for This Equipment?

The Ciena CNXA004AA (HECI/CLEI: 5SL1EF0DAA) is an SLC-5 DS3 WAN Card for the Ciena CNX-5 platform. Ciena acquired the CNX-5 product line from Catena Networks, so you may also see this card listed as the Catena CNXA004AA. Specifically, it provides a DS3 WAN uplink for the system. As a result, it connects subscriber access equipment in the field back to the carrier network.

DS3 WAN Connectivity

In addition, the card carries aggregated subscriber traffic over a DS3 (44.736 Mb/s) circuit, a long-standing standard in North American carrier networks. Consequently, operators can backhaul remote terminal sites over existing DS3 transport without new fiber builds.

Built for Loop Carrier Networks

Furthermore, the CNX-5 serves digital loop carrier deployments, which extend voice and data services from a central office to remote neighborhood cabinets. For background on how these systems work, see digital loop carrier. Therefore, the card suits telcos that still run CNX-5 equipment in their access plant.

Where the CNXA004AA Fits

Since the CNX-5 is a legacy platform, the secondary market is now the main source for spares and replacements. For this reason, operators keep these cards on hand to avoid service outages at remote sites. Telecom Leasing also stocks other legacy Ciena hardware, such as the Ciena B-720-1087-301 CN 4200 aggregation module.
